Ancient mass grave reveals how a pandemic wiped out a city 1,500 years ago

Ancient Antarctic ice is revealing a surprising new chapter in Earth’s climate story, stretching back 3 million years. By analyzing tiny pockets of trapped air and rare gases, scientists have discovered that while the planet cooled significantly—especially in the oceans—levels of key greenhouse gases like carbon dioxide and methane changed only modestly. This unexpected mismatch suggests other powerful forces, such as shifting ice sheets, ocean circulation, and Earth’s reflectivity, played major roles in driving long-term climate change.

The golden oyster mushroom may be a culinary hit, but it’s becoming an ecological problem. Scientists warn it’s spreading quickly through U.S. forests, where it outcompetes native fungi and reduces biodiversity. In just a decade, it has appeared in more than 25 states, largely due to human cultivation and transport. Its silent expansion is now raising concerns about long-term impacts on forest ecosystems.

A fresh mystery is unfolding inside Egypt’s pyramids. Researchers have discovered two hidden air-filled voids lurking behind the smooth eastern face of the Menkaure pyramid—an area long suspected to conceal something unusual. Using advanced, non-invasive techniques like radar and ultrasound, the team pinpointed these cavities with surprising precision, lending strong support to the idea that a secret entrance may exist.
